problems with port 4750, soap server in qlikview 11

Mon, 26 Jan 2026 18:19:17 GMT

Hello,

i want to install Qlikview Server v11.

Everything was running fine, licence is ok but the webserver is not running.

We have Blade Logic service on the service which uses port 4750.

When trying to start the webserver i have this error :

Service cannot be started. System.ServiceModel.AddressAlreadyInUseException: HTTP could not register URL http://+:4750/QVWS/Service/ because TCP port 4750 is being used by another application. ---> System.Net.HttpListenerException: The process cannot access the file because it is being used by another process

So i went to the config.xml of the webserver to change the port 4750 to 4850

<ConfigUrl>http://_:4850/QVWS/Service</ConfigUrl>

(everything else is by default)

and restarted the Qlikview Webserver service

Same error and still trying to connect to port 4750 for soap server.

How can i change that ?

and what may cause the https error ?

I found this before I found the solution so I thought I would update it here for other people's information.

You need to change the port in C:\Program Files\QlikView\Server\Web Server\QVWebServer.exe.config

Stephen

I had this problem today and this solution is still valid in 12.2 but the file location has changed:

C:\Program Files\QlikView\Server\Web Server Settings\QVWebServerSettingsService.exe.config

Change the port number to for example 4850.

Restart services and you're good to go.
